CAMEL-21716: Improve JBang Kubernetes plugin container image options

[christophd]

Description

• Set basic settings on JIB image builder
• Introduce configurable base image (default is still eclipse-temurin:17)
• Set image platforms on JKube properties
• Set proper image push registry on JKube properties

Target

• I checked that the commit is targeting the correct branch (Camel 4 uses the main branch)

Fixes CAMEL-21716

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally from root folder and I have committed all auto-generated changes.

I see the jkube.base.image is not a real jkube property from the jkube k8s page, it seems a wrapper for jkube.container-image.from, so perhaps why not set the jkube.container-image.from from --base-image ?

I had exported with --base-image=registry.redhat.io/quarkus/mandrel-for-jdk-21-rhel8:23.1 --registry-mirror=mirror.gcr.io it generated the following property, maybe there should be some validation for them.

<jkube.base.image>mirror.gcr.io/registry.redhat.io/quarkus/mandrel-for-jdk-21-rhel8:23.1
